Example 6.9. 

The example below is a PostgreSQL XA datasource configuration. The datasource has been enabled, a user has been added, and validation options have been set.
<datasources>
  <xa-datasource jndi-name="java:jboss/PostgresXADS" pool-name="PostgresXADS">
    <driver>postgresql</driver>
    <xa-datasource-property name="ServerName">localhost</xa-datasource-property>
    <xa-datasource-property name="PortNumber">5432</xa-datasource-property>
    <xa-datasource-property name="DatabaseName">postgresdb</xa-datasource-property>
    <security>
      <user-name>admin</user-name>
      <password>admin</password>
    </security>
    <validation>
      <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLValidConnectionChecker">
      </valid-connection-checker>
      <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLExceptionSorter">
      </exception-sorter>
    </validation>
  </xa-datasource>
  <drivers>
    <driver name="postgresql" module="org.postgresql">
      <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
    </driver>
  </drivers>
</datasources>
The example below is a module.xml file for the PostgreSQL XA datasource above.
<module xmlns="urn:jboss:module:1.1" name="org.postgresql">
  <resources>
    <resource-root path="postgresql-9.1-902.jdbc4.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
    <module name="javax.transaction.api"/>
  </dependencies>
